No one can remain even for a moment without activity, but usually actions that lead to complications and misery. Swami Paramananda explains what right action is and how it can solve our problems.
Take up one idea. Make that one idea your life -- think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, and this is the way great spiritual giants are produced. Others are mere talking machines.
-Swami Vivekananda
